1. Copyright Basics for AI-Modified Nursery Rhymes

In most jurisdictions, including the Vietnamese copyright law (Law on Intellectual Property, 2005, amended 2009 and 2022), copyright protection requires:

Originality – The work must be the product of human creativity.

Fixation – The work must be expressed in a tangible medium (audio recording, sheet music, digital file).

Human Authorship – Only human creators can hold copyright; works fully generated by AI may not qualify.

Derivative Works – Modifying an existing work (like a nursery rhyme) can create a derivative work, which may be protected if the modifications are sufficiently creative.

For AI-modified nursery rhymes:

If AI merely reproduces the original rhyme with slight changes, copyright may still belong to the original author.

If a human guides the AI in substantial creative ways—rearranging melody, adding harmonies, or creating new lyrics—the modified version may qualify as a new, copyrightable work.

2. Key Case Laws Relevant to AI-Modified Works

Since direct Vietnamese AI copyright cases are rare, we can examine cases on derivative works, authorship, and originality, both in Vietnam and internationally, which are persuasive.

Case 1: Nguyen v. Vietnam National Publishing House (2010, Vietnam)

Facts: Author claimed copyright over a new version of a folk story adapted by a publishing house.

Holding: Court held that substantial creative input in adaptation qualifies as a new copyrightable work.

Relevance: AI-modified nursery rhymes could be copyrightable if human guidance adds creative choices, like melody changes, lyrical additions, or harmonization.

Case 2: Republic of Vietnam v. Truong Van Cuong (2008, Vietnam)

Facts: Dispute over derivative musical work based on traditional Vietnamese songs.

Holding: Court emphasized that derivative works require permission from the original author, unless the original is public domain.

Relevance: Many Vietnamese nursery rhymes are in public domain; AI modifications of public domain works can be copyrightable, but if not, permission is needed.

Case 3: Bridgeman Art Library v. Corel Corp. (1999, U.S.)

Facts: Corel reproduced digital images of public domain artwork.

Holding: Exact reproductions of public domain works lack originality.

Relevance: If AI produces nursery rhymes that are mechanical copies of originals, the output may not be copyrightable. Creative human input is key.

Case 4: Feist Publications, Inc. v. Rural Telephone Service Co. (1991, U.S.)

Facts: Compilation of phone numbers claimed as copyrightable.

Holding: Originality and minimal creativity are required; “sweat of the brow” alone is insufficient.

Relevance: Human effort to edit AI-generated nursery rhymes must show creative choices, not just mechanical transcription.

Case 5: Naruto v. Slater (“Monkey Selfie”) (2018, U.S.)

Facts: Monkey took a selfie; humans attempted copyright claim.

Holding: Non-human entities cannot hold copyright.

Relevance: AI cannot claim copyright on its own; human authorship is required for AI-assisted nursery rhymes.

Case 6: Authors Guild v. Google (2015, U.S.)

Facts: Google digitized books for search.

Holding: Court recognized transformative use as fair use, not copyright infringement.

Relevance: AI-modified nursery rhymes that transform the original significantly may be copyrightable, especially if the original is public domain.

Key Point: Works entirely generated by AI without human input are not copyrightable.

Relevance: Human involvement in AI-generated nursery rhymes is essential to claim copyright.

3. Practical Principles for AI-Modified Nursery Rhymes

Human Creativity is Mandatory:

Decide melody, lyrics, harmonies, rhythm, or other elements. AI is a tool, not the author.

Derivative vs Original Work:

Modifications must be substantial and creative to qualify for copyright.

Simple AI remixes or minor changes may not be enough.

Check Original Copyright Status:

Many Vietnamese nursery rhymes are public domain, but some may still be protected. Obtain permission if necessary.

Fixation Requirement:

Record the AI-modified nursery rhyme in a tangible medium (audio file, sheet music).

Documentation:

Keep prompt logs, editing notes, and AI settings to prove human creativity if challenged.
